[Histonet] warthin starry stain

[Lee & Peggy Wenk]

It's probably because the doctor/nurse is letting the biopsy dry out before they place it in formalin. Even setting a minute on a pad will do this. We've seen this also with kidney biopsies.

No way to correct it after the fact. No way to make the W/S stain work. The tissue HAS to be placed in the fixative IMMEDIATELY.

You might try the Giemsa or Diff-Quik stain. Sometimes they will still stain the H. pylorii after this drying out.

  I am having some trouble with our Warthin-Starry stain.  The peripheri of the gastric biopsy is not getting stained.  The rest of the specimen is well stained.  I am not sure if I need to lengthen the impregnation time or the developer time.  I have never had this happen before.  Any suggestions would be greatly appreciated.
